SINGLE-TUBE TIRE.

Application filed November 4, 1921. Serial No. 512,897.

To all who/m, dit may cof/wem;

Be it known lthat I, FRANCoIsoo Rosn'rn, Mexican, citizen of Pachuca,Hidalgo, reslding at Tulancingo, in the countyv of Tulancingo and Stateof Hidalgo, Mexico,.have

Single-Tube Tires, of which the following is la" specification.

rlhis invention relates to single tube'tires,

andione of the principal objects of the in-l vention is to produce adevice of this nature in which the annular aperture between the rim andthe shoe may be closed by an innatable element containing the valvemechanism' for inflating the shoe also.l

Another object is to construct a tire ofA this nature'in whichshall beplaced means 'for automatically stopping small punctures of the tire. f

Another object is to construct a device of this nature which shall besimple of construction, cheap to manufacture, and -highly 'eflicient forthe purpose for which it is designed. v

With these and other objects in view, the invention 4resides in certainnovel construction-and arrangement and combination of parts, theessential features of which are ,i hereinafter fully described, areparticularly pointed out in the appended claims, and are illustrated inthe accompanying drawing, in which Figure 1 is a vertical sectional viewof the tire with the closure member in nonclosing position. Figure 2 isa sim1lar view with the parts in closed position.

.F'gure 3 is-asimilar View on the line ofthe valve mechanism. l j

lfigure 4 is'a section of the tire at right angles to the axis ofrotation.

Like characters of reference referto like parts in all views.

Referring to the drawing in detail, 10 represents the body portion ofthe tire which is constructed similar to any well known shoe and may beprovided with any desired mannel` of tread surface.' The-tire 10 isprovided with two beads 11 and 12 and with a Acentral lannular opening13 between twol in' wardly curved flanges 14. A cover member 15 of thickcanvas or any othersuitable material is secured to the bead 11 andadapted to fold the flap against the bead 12, the latter bead beingraised at 16 for this purpose. It will be noted that the elements and 14define a semi-circular space 17 in whichy there lies a small inflatabletube 18. A valve 19 permits air tobe forced into the tube 18 and a valve20 is provided with a spring so that when the pressure in tube 18 risesabove, a predetermined amo-unt of ain may escape therefrom through saidvalve 20. Valve 2() n registers with the groove 13 and a lining of oilcloth or soft rubber or any other suitable material indicated by thenumeral 21'cove1s the entire inner surface of the tube and a similarIlining is indicated at 22' on that l face of the flap 15 which abuts thebead 12.

In operation the bead 11 is rst adjusted to position, flap 15 isbroughtflrmly into the seat 16 and then the bead 12 is placed in the.the member 18 valve 20 permits escape of air into the main chamber ofthe tire as to 'inflate' the latter.

In case of slight punctures the flexible lining 21 will extrude itselfinto the puncture so as to'stop up the same and prevent leakage. Alsoincase of punctures the lining 21 forms a .suitable means for anchoringpatches and the like. v 'f The memberk 15 makes with the seat 16 theprincipal obturation of the tire-and the eflicien'cy of this obturationis increased in proportion with the pressure of '.the air blown into thetire. This invention is also applicable to detachable tires. What is'claimed is:'-

1. A tire of the class described comprising a bodyportion formed withflanges, a flap se' cured to one of said flanges and-seated againstv theother of said flanges and a tube securedA to said flap as and for thepurpose set forth. j

2. A' tire comprising an annular slot, a movable flap -secured adjacentthereto, an inflatable tube adapted to close said slot, and meanswhereby said tube may be inflated, and means whereby air may be expelledfrom said tube to, the main chamber of said tire, whenthe pressure insaid tube has reached a predetermined point.

In testimony whereof I have signature.

l10 so aflixed my rjRANorsoo aosur'n.
